This disease cant be transmitted only given to you by bad choices of the mother. It is a pattern of birth defects, learning and behavioral problems that are in result of maturnal alcohol use during pregnancy. The only way a baby can get a disease is through the mother drinking during pregnancy. When you drink alcohol during pregnancy, even in the early stages it enters your bloodstream and reaches the fetus fetus by crossing through the placenta. Since a fetus metabolizes alcohol more slowly than an adult does, the babies blood alcohol concentrations are higher than those in the mothers body. Alcohol also causes issues with the babies delivery of oxygen and nutrition to developing tissues, organs and the babies brain.
